Disclosure of Invention

For overcoming the defects of the prior art, the utility model aims at providing a slag removal device for a slab heating furnace, which can clean the furnace without cooling and can directly clean sundries from the bottom of the flame path to the outside of the flame path.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

a slag removal device for a slab heating furnace comprises an air inlet pipe, a slag discharge pipe, a hose and a hoisting mechanism, wherein the air inlet pipe is connected with the hose, and a hoisting ring is fixed at the top of the slag discharge pipe;

hoisting machine constructs including wire rope, lifting hook, pulley, support, hoist engine, and pulley fixed connection is on the support, and the support bottom is fixed with the hoist engine, and the hoist engine is connected with wire rope, and the wire rope other end walks around pulley and lifting hook fixed connection, and the lifting hook is used for the hook hoisting ring.

The bottom of the bracket is connected with a waste residue hopper car.

The upper part of the slag discharging pipe is fixedly connected with an operating handle.

The support be L shape structure, including crossbeam, longeron, strengthening rib, crossbeam and longeron mutually perpendicular are fixed, the welding has the strengthening rib between crossbeam and the longeron, crossbeam both ends, the equal fixedly connected with pulley in longeron bottom.

The included angle between the air inlet pipe and the slag discharging pipe arranged on the surface of the furnace top is less than 45 degrees.

Compared with the prior art, the beneficial effects of the utility model are that:

a slag removal device for slab heating furnace adopts the mode of sweeping and sweeps clearance debris, need not to lower the temperature and can carry out the cleaning operation to the stove in. Can directly clear up the debris that is less than slag pipe diameter in the flame path to the flame path outside from the flame path bottom, rather than clear into the chute district. The waste residue hopper car is adopted to receive the sundries, so that the difficulty in cleaning the site environment can be reduced, and the sundries can be conveyed directly conveniently. The slag discharge pipe can be arranged below the air inlet pipe by utilizing the hoisting mechanism, the installation of operators is not needed, the personal safety of the operators is ensured, and the purposes of cooling and cleaning sundries are achieved.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

Referring to fig. 1, the slag removing device for the slab heating furnace comprises an air inlet pipe 2, a slag discharge pipe 1, a hose 9 and a hoisting mechanism, wherein the air inlet pipe 2 is connected with the hose 9, and a hoisting ring 4 is fixed at the top of the slag discharge pipe 1. The included angle alpha between the air inlet pipe 2 and the slag discharging pipe 5 arranged on the surface of the furnace top is less than 45 degrees, compressed air is conveyed to the air inlet pipe 2 through a hose 9, and the air inlet pipe 2 sends the compressed air into the slag discharging pipe 5 on the surface of the furnace top. The length of the vertically arranged slag discharge pipe = the height of the carbonization chamber + the thickness of the furnace top +700mm.

Hoisting machine constructs including wire rope 12, lifting hook, pulley 8, support, hoist engine 10, and pulley 8 fixed connection is on the support, and the support bottom is fixed with hoist engine 10, and hoist engine 10 is connected with wire rope 12, and pulley 8 and lifting hook fixed connection are walked around to the wire rope 12 other end, and the lifting hook is used for hook hoist and mount ring 4. The support bottom is connected with waste residue hopper car 11, and waste residue hopper car 11 sets up in the row's of sediment pipe 1 below, the convenient debris of clearing up of transporting. The upper part of the slag discharging pipe 1 is fixedly connected with an operating handle 3, an operator can hold the operating handle 3 by hand to adjust the horizontal position of the slag discharging pipe 1 from the side part, so that the horizontal position corresponds to the pipe orifice position of the slag discharging pipe 5.

The support is L shape structure, including crossbeam 6, longeron 7, strengthening rib, and crossbeam 6 is fixed with longeron 7 mutually perpendicular, and the welding has the strengthening rib between crossbeam 6 and the

longeron

7, and 6 both ends of crossbeam, the equal fixedly connected with pulley 8 in longeron 7 bottom.

The hoisting mechanism is utilized to send the hoisting ring 4 to the bottom of the fire channel, the included angle alpha between the air inlet pipe 2 and the slag discharging pipe 5 arranged on the surface of the furnace top is kept to be less than 45 degrees so as to ensure enough air inlet amount, compressed air is conveyed to the air inlet pipe 2 through the hose 9, and the air inlet pipe 2 sends the compressed air to the slag discharging pipe 5 on the surface of the furnace top. Note that the front of the tapping pipe 5 cannot be aimed at a person or other equipment. Compressed air is opened for air supply, and air at the pipe orifice of the slag discharging pipe 5 is forcibly and continuously conveyed away by the compressed air, so that air at other parts in the pipe is continuously supplemented to the position, vacuum (namely negative pressure) is rapidly formed between the pipe orifice of the slag discharging pipe 1 and the pipe orifice of the slag discharging pipe 5, strong suction is generated around the pipe orifice at the bottom of the slag discharging pipe 5, and sundries such as broken bricks and ash blocks which are smaller than the diameter of the slag discharging pipe 5 are sucked into the pipe and rapidly discharged.
